This invention relates to multiple fastening devices using a series ofinterengageable elements.

Usually the elements on one side of such a device carry projectionswhich engage a suit- 10 necessitates a ,wide and bulky fastening deviceoccupying a comparatively largespace "especially where it is used as ashoe fastener. Another objection to having the projections or hooks, inthe particular case cited, placed min the same plane with the anchoringportions of their respective elements is the tendency for saidprojections to become entangled with outside objects when the fasteningdevice isopen. This might result in bending 20 or otherwise distortingthe hooks and thereby making the fastener inoperative. The object of myinvention is to overcome the aforementioned objections and to produce amultiple fastening device which is more compact in form and less apt tobecome inoperative when not in use.

For a detailed description of a preferred form of my invention,reference may be had to the following specification and to theaccompanying drawings forming a part thereof in which:

Fig. 1 is a plan view of the multiple fastening device; I

Fig. 2 is a sectional view taken on the line A.-A of Figure 1;

Fig. 3 is a bottom plan view on an enlarged scale of the fastener partlyin sectlon showing the members of the opposite sides in an interengagedposition;

Fig. 4 is a sectional view of the sl der.

Referring to the drawings, a multl le fastener is shown comprising apair o fabric stringers 1 which may be of any desired material but arereferably formed of square woven fabric olded about a cord or otherflexible member 2 to afford a good grip v for the metallic elements inwhich this 1nvent1on is particularly concerned. Two series of elements 3and 4 are preferably employed, the

P former comprising anchoring portions 5 formed by suitably bendingsheet metalsuch as German silver, or brass, which may be plated, aboutthe corded edge of the strin rs as shown in the drawings, the sheetmetafi one side of the plane of the anchoring or.-

tions, being further bent 'or folded-to orm a keeper portion 6 providedwithan eye indicated at 7. The eye? is located partly in the upstandingflange 8 and partly in the body of the keeper portion, as clearlyillustrated in Figure 2 'of the drawings.

*The second series 4 of the metallic elements are preferably formed fromsheet metal by folding the same in, the same manner as the series ofeyed members but the bent-under-portions thereof are preferably formedso as to constitute a hook 9 which occupiesa plane to one side of theanchoring portions 10 of the second series of elements,

theh ks of course being located and projecting laterally so as toregister and be interenga cable with the series 0 elements.

The two series of elements are adapted to be operated by a sliderindicated generally at 11, of old and well-known construction andcomprises essentially top and bottom plates 12 and 13 pinned orotherwise secured together as indicated at 14 to form two con- Iergentguiding channels. The top and bottom plates are secured in the desiredspaced a art relation by a block 15 which is prefera 1y provided with agroove. '16 for passage of the hooks 9.

Any suitable form of stop members may be provided at the upper and lowerends of th series of elements, headed pin 17 being eyes 7 in the othershown at the upper end of the two strin ersl Each of the elements ofboth the series 3 and 4,has at its lower end a projection or will beseen, therefore, that the projections '18, serveto prevent lateraldisplacementof the elements in much the same manner as the hook 9 andeye 7 when in locked relation serve to prevent longitudinal displacementofthe elements' V a In operation when the slider 11 is pulled.

downwardly the elements are disengaged a and when the slider is movedupwardly the' elements are engaged .by introduction of the hook membersinto the eye members in a manner that will be obvious. llhe hooks andeyesare so proportioned that when they are engaged it is impossible todisengage them by a direct lateral pull in opposite direc tions,

it will be apparent that the device is simple to manufacture, iscompact, and presents a very narrow width of metal to the eye which isdesirable from a manufacturing standpoint, and that the elements orfasteners, per se, are of a sturdy construction not likely to be bent ordeformed in service and rendered inoperative. While the elements of thefastening device have been described as being formed out of bent metal,it will be understood that any suitable material can be used such ascast metal, etc.

It will of course be. obvious that man changes may be made in thedetails of the construction without departure from the principlesunderlying this invention, and

reference should therefore be made to the accompanying claims for anunderstanding of the scope of the invention. I

Having thus described my invention, what I claim and desire to protectby Letters 'Patcut is:

1. A multiple fastening device having two stringers, a series ofinterengageable elements having anchoring portions secured to each ofthe stringers, some of the interengageable elements having hook portionsand other of the interengageable elements having eye portion's, theinterengageable elements being arranged on the stringers so that a hookportion is adapted to engage with an eye portion; said hook and eyeportions being located to one side of the plane of their respectiveanchoring portions and being so constructed so that the hook portionsand eye portions are engageable by edgewise convergent movement of thestringers. 1

2. A multiple fastening device having at least two stringersya seriesof'interengageable elements having anchorin portions secured to thestringers, some 0% the interengageableelements having hook-portions andother of the interengageable elements having eye portions, theinterengageable elements being so positioned on the stringers and soconstructed that the hook portions of one stringer are engageable witeye portions on the other stringer, said hook portions and e e portionsbemg oflset from the plane of t e anchoring portions, the hook portionsbeing flat and extending in a direction from the other stringer.

3. A multiple fastener having at least two stringers, member havinganchoring portions clamped on each of the stringers, some of saidmembers having hook portions located at one side of the plane of theanchoring portions, and other of said members having recessed portionslocated at one side of the plane of the anchoring portions, said hookmembers and said eye members being so arranged on the stringers and soconstructed that interengagement of the hooks with the eyes may beeffected by convergent edgewise,-

movement of the stringers.

4. A multiple fastening device having two stringers, interengageableelements having anchoring portions secured to each of the stringers,some of the elements having hook portions and other of the elementshaving eye 'rtions, the elements being arranged on e stringers so thatthe hook portions of the elements of one string r may be engaged withthe eye portions 0 the elements of the other stringer, the hook portionand the eye portion of eachof the elements being y in a differentplaneifrom the anchorin portion of the respective elements, the hooportion being flat and extending in a direction from the stringer towhich it is fastened toward the other stringer;

5. A separable fastener comprising a pair of stringers, two series ofunlike elements, secured respectively to the adjacent edges of the twostringers, and having interengageable portions located and contacting ina plane oflfset from and parallel to the plane ofthe stringers, theinterengageable portions being so constructed as to be engageable byconvergent edgewise movement of the stringers.

6. Aseparable fastener comprising a pair of stringers, two series ofunlike elements,
